Abstract

Provided is a display device including: a rectangular display panel; a first film-like printed circuit board including a first terminal portion, the first film-like printed circuit board extending from one side of the rectangular display panel in a direction; a rectangular touch panel provided so as to be opposed to the rectangular display panel; and a second film-like printed circuit board including a second terminal portion, the second film-like printed circuit board extending from one side of the rectangular touch panel in the direction, the one side of the rectangular touch panel corresponding to a side parallel with and adjacent to the one side of the rectangular display panel, the first terminal portion and the second terminal portion being provided so that a connecting direction of the first terminal portion is different from a connecting direction of the second terminal portion.

Claims (19)

1. A display device, comprising:

a rectangular display panel;

a first film-like printed circuit board including a first terminal portion to which a connector is to be connected, the first film-like printed circuit board extending from one side of the rectangular display panel in a direction orthogonal to the one side of the rectangular display panel without folding of the first film-like printed circuit board;

a rectangular touch panel provided so as to be opposed to a viewing side of the rectangular display panel; and

a second film-like printed circuit board including a second terminal portion to which a connector is to be connected, the second film-like printed circuit board extending from one side of the rectangular touch panel in the same direction orthogonal to the one side of the rectangular display panel without folding of the second film-like printed circuit board, the one side of the rectangular touch panel corresponding to a side parallel with and adjacent to the one side of the rectangular display panel,

the first terminal portion and the second terminal portion being provided so that a connecting direction of the connector for one of the first terminal portion and the second terminal portion is different from a connecting direction of the connector for another of the first terminal portion and the second terminal portion.

2. A display device according to claim 1 , wherein the first terminal portion and the second terminal portion are positioned between two lines extending from two parallel sides connecting with both ends of the one side of the rectangular display panel.

3. A display device according to claim 1 , wherein the connecting direction of the connector for the one of the first terminal portion and the second terminal portion is a direction defined by inclining the direction orthogonal to the one side of the rectangular display panel toward one end of the one side of the rectangular display panel.

4. A display device according to claim 3 , wherein the connecting direction of the connector for the another of the first terminal portion and the second terminal portion is the direction orthogonal to the one side of the rectangular display panel.

5. A display device according to claim 3 , wherein the connecting direction of the connector for the one of the first terminal portion and the second terminal portion which is smaller in width is a direction defined by inclining the direction orthogonal to the one side of the rectangular display panel toward the one end of the one side of the rectangular display panel.

6. A display device according to claim 3 , wherein the connecting direction of the connector for the another of the first terminal portion and the second terminal portion is a direction defined by inclining the direction orthogonal to the one side of the rectangular display panel toward another end of the one side of the rectangular display panel.

7. A display device according to claim 1 , further comprising a transparent plate bonded to a surface of the rectangular touch panel on an opposite side with respect to the rectangular display panel.

8. A display device according to claim 1 , wherein the first terminal portion of the first film-like printed circuit board extends at a part of the first film-like printed circuit board in a direction substantially parallel to the one side of the rectangular display panel, and the second terminal portion of the second film-like printed circuit board extends at a part of the second film-like printed circuit board in a direction substantially orthogonal to the one side of the rectangular display panel so that a connecting direction of the connector for the first terminal portion differs from a connecting direction of the connector for the second terminal portion and enables connection of the respective connectors for the first and second terminal portions without interference therebetween.

9. A display device according to claim 8 , wherein a width of the second terminal portion in the extension direction thereof is smaller than a width of the first terminal portion in the extension direction thereof.

10. A display device according to claim 8 , wherein the display device forms a part of a mobile phone.

11. A display device according to claim 1 , wherein the first film-like printed circuit board has substantially a first thickness throughout the extent of the first film-like printed circuit board, and the second film-like circuit board has substantially a second thickness throughout the extent of the second film-like printed circuit board so that the first and second film-like circuit boards have no portion folded back upon another portion thereof and resulting in a change of the thickness of a respective film-like circuit board thereat.

12. A display device according to claim 11 , wherein the first terminal of the first film-like printed circuit board is provided at a part of the first film-like printed circuit board and extends in a first direction which is substantially parallel to the one side of the rectangular display panel, and the second terminal portion of the second film-like printed circuit board is provided at a part of the second film-like printed circuit board so as to extend in a second direction which is substantially orthogonal to the one side of the rectangular display panel so that the connecting direction for the connector of the first terminal portion differs from the connecting direction of the connector for the second terminal portion so as to enable connecting of the connectors for the first and second terminal portions without interference therebetween.

13. A display device according to claim 11 , wherein the display device forms a part of a mobile phone.

14. A display device according to claim 1 , wherein the display device forms a part of a mobile phone.
